Recent wildfires in Los Angeles have left behind more than charred landscapes and smoky skies—they’ve also created water safety challenges that many residents are experiencing for the first time. In the aftermath of the fires, safe water advisories have been issued in some areas, warning residents to boil water or avoid it altogether for certain uses.
These advisories, while common in regions with frequent hurricanes or flooding, are unfamiliar to many Angelenos. Yet they play a crucial role in protecting public health during and after natural disasters. Understanding why these advisories are issued, what they mean, and how to respond can help ensure your family stays safe when water quality is uncertain.
The Connection Between Wildfires and Unsafe Water
Water safety can become a significant concern during wildfires for several reasons:
- Low Water Pressure: Firefighting efforts require massive amounts of water, which can reduce water pressure in pipes. This drop in pressure allows contaminants to backflow into the system.
- Ash and Debris Contamination: Wildfires produce large amounts of ash, soot, and other debris that can wash into reservoirs and water treatment facilities.
- Damaged Infrastructure: Intense heat and fire damage can compromise water pipelines, creating cracks or leaks that allow bacteria, chemicals, and other harmful substances to enter the water supply.
These disruptions can lead to contamination with harmful pathogens, chemicals, and heavy metals, making water unsafe for drinking, cooking, or other uses.
What Are Safe Water Advisories?
Safe water advisories are precautionary alerts issued by local water authorities when water safety cannot be guaranteed. They fall into three main categories:
- Boil Water Advisory: Issued when there’s potential biological contamination, such as bacteria or viruses, which can be killed by boiling.
- Do Not Drink Advisory: Issued when water contains harmful chemicals or toxins that boiling cannot remove. Bottled water is necessary for drinking and cooking.
- Do Not Use Advisory: Issued in extreme cases when water is unsafe for any use, including bathing or washing.
Signs Your Water May Be Unsafe
Even without an official advisory, water can become unsafe to use. Watch for these signs:
- Strange Odor: A chemical, musty, or chlorine-like smell.
- Discoloration: Water that appears brown, yellow, or cloudy.
- Unusual Taste: A metallic or off-putting flavor can indicate contamination.
When in doubt, it’s best to err on the side of caution and treat or replace your water supply.
What You Need to Know During a Safe Water Advisory
If a safe water advisory is issued in your area, follow these guidelines to protect yourself and your family:
Drinking and Cooking
- Boil Water: Bring water to a rolling boil for at least one minute (three minutes at higher altitudes) to kill bacteria and viruses.
- Use Bottled Water: When advised not to drink tap water or if the water smells, looks, or tastes unusual.
Bathing and Hygiene
- Adults and Older Children: Bathing or showering is generally safe as long as water is not ingested.
- Infants, Young Children, or Immunocompromised Individuals: Use boiled or bottled water to reduce the risk of skin or eye irritation.
Brushing Teeth
- Always use boiled or bottled water for brushing teeth, as untreated water can harbor harmful contaminants.
Washing Clothes
- Washing clothes is generally safe unless the water is visibly discolored or has a foul odor. Delay washing sensitive items, like baby clothes or towels, until water quality improves.
Cleaning Food and Dishes
- Wash fruits, vegetables, and kitchenware with boiled or bottled water to avoid contamination. Avoid using untreated water, especially when food comes into direct contact with it.
Why Following Safe Water Advisories Is Critical
Drinking or using contaminated water can lead to serious health risks, including gastrointestinal infections, chemical poisoning, or exposure to heavy metals. These risks are especially high for vulnerable populations, including young children, pregnant women, and individuals with chronic illnesses or weakened immune systems.
Local water authorities issue these advisories as a precaution to protect public health. By following them closely, you reduce the risk of illness and ensure your water is safe for daily use.
Stay Informed and Prepared
Navigating a safe water advisory can be challenging, especially if it’s your first time. These tips will help you stay informed and prepared:
- Check Updates Regularly
- Visit your local water utility’s website or call their hotline for the latest information about advisories and when they’re lifted.
- Sign up for emergency notifications through your city or county to receive updates.
- Be Prepared
- Keep a three-day supply of bottled water (one gallon per person per day) on hand for emergencies.
- Invest in water purification tablets or a portable filtration system for extended disruptions.
- Inspect Your Plumbing
- After wildfires or other disasters, check for leaks, sediment buildup, or discoloration in your tap water. Report any issues to your local water provider immediately.
A New Reality for Many Los Angeles Residents
For many Los Angeles residents, safe water advisories may feel like uncharted territory. However, as extreme weather and natural disasters become more common, these advisories are likely to play a larger role in ensuring public safety.
By staying informed, treating water as needed, and taking precautions, you can navigate these situations confidently. And remember: when in doubt, bottled water is always the safest choice.
